Description

Technical Field

[0001] This utility model relates to the field of packaging bags, and in particular to a portable plastic food packaging bag. Background Technology

[0002] Food packaging bags are a type of packaging design. They were developed to facilitate the preservation and storage of food. Food packaging bags are thin-film containers that come into direct contact with food and are used to hold and protect it. Most food packaging bags currently in use are openable; that is, the bag is flat when not in use and unfolds into a box-like structure when needed to hold food. However, current packaging bags still have the following technical problems in practical use: The width of the current packaging bags is not easily adjustable. When some block-shaped food is placed inside the bag, the sides of the food cannot meet the inner walls of the bag. This causes the food to slide left and right with the bag's movement during transport, potentially damaging the food and affecting its edibility. Furthermore, the sliding of the food changes the center of gravity of the bag and food when lifting, affecting the user's lifting ability, making it more difficult to lift and increasing the bag's shaking, thus making it inconvenient to use. Utility Model Content

[0003] The present invention aims to provide a portable plastic food packaging bag to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0021] like Figures 1 to 6The portable plastic food packaging bag shown includes a bag body 1, which includes an outer plastic layer 11, an absorbent layer 12, and an inner plastic layer 13. A roll rod 2 is fixedly connected to the left and right sides of the bag body 1. A pressure rod 3 is rotatably connected to the roll rod 2. The upper end of the pressure rod 3 is rotatably connected to the roll rod 2 via a rotating shaft. A rubber friction pad 4 is connected to the pressure rod 3. The pressure rod 3 is made of plastic with elastic deformation capability. A slot 10 is provided at the bottom of the roll rod 2. A rotating rod 7 is rotatably connected to the pressure rod 3. A locking plate 8 is connected to the rotating rod 7. The locking plate 8 cooperates with the slot 10, meaning the locking plate 8 can be inserted into the slot 10. The absorbent layer 12 is connected to the outer plastic layer 11, and the inner plastic layer 13 is connected to the absorbent layer 12. The inner plastic layer 13 is made of environmentally friendly and harmless plastic. The inner plastic layer 13 has several sets of water-permeable holes 14, which are staggered along the sidewall of the inner plastic layer 13. No water-permeable holes 14 are required at the bottom of the inner permeable layer.

[0022] The rotating rod 7 is connected to a lever plate 9. The distance between the lever plate 9 and the locking plate 8 is greater than the distance between the locking groove 10 and the outer wall of the winding rod 2. When the locking plate 8 is engaged in the locking groove 10, the lever plate 9 is located on the side of the winding rod 2. Figure 2 As shown, the card plate 8 can be slid out of the card slot 10 for easy access. The bag body 1 is connected to a placement frame 5, into which an information card containing food or user information can be inserted for easy identification of food information. The bag body 1 is also connected to a lifting strap 6.

[0023] The following is Figure 1 Taking the left-side coil rod 2 as an example, the use of coil rod 2 and pressure rod 3 will be described in detail: Figure 1 and Figure 2As shown, at this time, the card plate 8 is inserted into the card slot 10. Due to the friction between the card plate 8 and the side wall of the card slot 10, as well as the elasticity of the pressure rod 3, the card plate 8 will not easily rotate forward and slide out of the card slot 10. Consequently, the pressure plate will not rotate clockwise relative to the winding rod 2. When it is necessary to adjust the width of the bag body 1, rotate the actuating plate 9 forward. The actuating plate 9 rotates forward, causing the rotating rod 7 and the card plate 8 to rotate forward relative to the pressure rod 3, thereby causing the card plate 8 to slide out of the card slot 10. At this time, the pressure rod 3 can rotate clockwise relative to the winding rod 2. Rotate the pressure rod 3 180 degrees clockwise relative to the winding rod 2 so that the pressure rod 3 is above the winding rod 2. Then rotate the winding rod 2 so that the bag body 1 is wound up on the winding rod 2. After winding up a bag 1 of appropriate width, rotate the pressure bar 3 180 degrees counterclockwise relative to the winding bar 2. At this time, the bag 1 wound on the winding bar 2 is located between the pressure bar 3 and the winding bar 2. The pressure bar 3 and the winding bar 2 clamp the wound bag 1. The rubber friction layer can also increase the friction between the pressure bar 3 and the wound bag 1, further improving the clamping stability and preventing the wound bag 1 from easily unfolding. Then, align the clamping plate 8 with the clamping slot 10 and rotate the actuating plate 9 backward to insert the clamping plate 8 back into the clamping slot 10, so that the pressure bar 3 can stably clamp the wound bag 1. Similarly, the width of the right side of the bag 1 can be adjusted to complete the adjustment of the width of the bag 1.

[0024] When hot food is placed inside the bag 1, small water droplets will condense on the inner plastic layer 13 due to the heat emitted by the food. These small water droplets will accumulate on the inner plastic layer 13 and then flow downwards when they reach the water-permeable hole 14. They will then come into contact with the absorbent layer 12 and be absorbed by the absorbent layer 12, preventing the small water droplets from flowing to the bottom of the bag 1 and accumulating, which would affect the taste of the food.

[0025] When using the bag, adjust the width of the bag 1 according to the food to be placed inside, then open the bag 1 and put the food inside the bag 1; alternatively, you can open the bag 1 first, put the food inside the bag 1, and then adjust the width. Then insert the information card into the placement slot to complete the packaging of the food.
